Earlier this evening I let my (new - 3 weeks ago) woodstove get a little hotter than I typically do after re-stocking the firebox, around 800F (which as I read these forums understand that this isn't a temperature to necessarily be concerned about). I adjusted the air intake to get the temperature down to the sweet spot that I was after. I have just noticed a slight discolouration patch on the top of the stove (see image). Wondering what your thoughts are and whether this is anything to be concerned about. I guess my primary concerns are:

- Is this indicative of any damage?
- Would you expect this discolouration to fade?
- If cosmetic, can this be touched up?
